by Andrew HamiltonCocktail jazz with an odd combo of a tinkling piano and a wah-wah guitar performing the main instrumental duties. Classic mood and soundtrack music with enough contemporary juices for play on smooth jazz stations. Electronic effects fill out some, while giving an eerie feeling to other tracks. This is excellent rainy day or thinking music, with Stefani, Annika, and Billy Valentine's voices mixed with brain surgeon precision throughout the 13 tracks.
